You pick up a book that looks interesting and begin reading. The main character, Sally, is a complex individual who can be friendly, but also rude, motivated but lazy, fun to be with but challenging. At the beginning you are intrigued by Sally because you realize that her life is about to change.
Her best friend is manipulating her financially and emotionally. Sally is being forced into deciding between going on a vacation with the friend, who wants Sally to pay for the whole thing, or buying herself a badly needed new car. Meanwhile Sally’s son has lost his job and is moving back home. Sally loves him, but can’t live with him for his sloppiness drives her crazy.
As the story progresses you begin to understand why Sally behaves the way she does as each impediment arises. You root for her when you think she makes the right decision and lament the poor ones that get Sally in trouble. Ove the course of the story, you see Sally grow and change.
That is called the character arc and it’s what makes characters dynamic: readers want to see them experience challenges that force them to evolve over the course of the story.
Your task is to write a story in which a character is met with a series of difficulties that either are overcome or not. If overcome, then the character must change in some small way. If not, there still must be change, but is it positive or negative change?
At the end the character must be different in some way. It should be large enough that the change affects behavior, status and beliefs.
Have fun with this one.
